How about a little more general approach? I would propose the following:

If a way has a note with an access restriction, the segments of the way
that connect to the node have the access restrictions from the node
placed on them.

This would have the following advantages:
- With such an a feature, you would not only handle bollards, but also
gates and other obstacles.

- You need not to use a default access restrictions, but you can rely on
the restriction in the data base. If no access restriction is defined in
the data, you can still imply one via the style file. (I don't know,
whether such a style rule would be applied in time before you place the
restrictions on the way?)

- The maps would be still usable, if it is run with with false vehicle
settings. (Only the car setting seems to provide a real good routing, so
to get good a bicycle routing, you need a specially generated map run in
the car-mode).

What do you think about such a modification?
